I am thinking about putting a mesh screen over the tank to prevent certain fish from jumping out. Marbel hatchets... How will this effect the lighting and my plants? will the lighting be less effective? If so, to what degree?
There is a transparent plastic net that is available and it does not reduce much intensity at all, if any if you use the 1/4 or larger hole size. I used to use it as a marine aquarium keeper and it never effected light intesity...we spent a lot of time measuring it with a ton of different light meters and never seen a difference.
